IMPROVEMENT IN WASH-BOlLERS.

Specification forming part of Letters Patent N0- l64,875, dated June22,1875; application filed March 11, 1875.

To all whom it may concern: I

Be it known that 1, JOHN RIETH, of Lansing, in the county of Allamakeeand State of Iowa, have invented certain new and useful Improvements inWVash-Boilers, of which the following is a specification:

This invention relates to that class of wash-boiler attachments"designed to be placed within the boiler proper, which receives theclothes to be cleansed, and in which the attachment is constructed withanarrow chamber formed of two vertical sheet-metal plates perforated attheir top, and each having at its bottom a, perforated flange, whichprojects laterally from the same in such manner that when the attachmentis arranged within the vessel or boiler proper, and the clothes andwater placed therein, the water will, by boiling, circulate upwardlythrough the vertical chamber and out of the top perforations, and thencedownwardly through the clothes and into the vertical chamber through theperforations in the lateral flanges, the operation being continuous, andthe effect produced being athorough cleansing ofthe clothes,

caused by the rapid passage of the water through the same.

Theobject of the present invention is to prevent the clothes filling orstopping up the perforations in the lateral flanges of the verticalwalls forming the chamber, and also to prevent the clothes coming incontact with the bottomof the boiler through the perforations in thelateral flanges, which it has been found injures and soils the clothes,due to the two metals coming together at that point, which producesoxidation, or rust; and this end is accomplished by arranging guards orshields over and immediately above the lateral flanges of the verticalchamber, said shields or guards terminating, at such a distance from theouter horizontal edge of the late\,tl flanges, as to leave sufficientspace between the inner surface of the walls of the boiler and theguards in order to permit the .free passage of the water through theperfor- In the accompanying drawings, Figure 1 is a perspective view ofmy invention; and

Fig. 2 is a transverse section of the attach allel, or nearly so, toeach other, and having their upper ends brought together and providedwith any desired number of perforations c, while their lower ends areeach constructed with a lateral flange, d, provided with a series ofperforations, e, in such a manner that when the attachment is arrangedwithin the boiler, and the clothes and water placed therein, the latterwill, upon boiling, circulate in a continuous manner up the verticalchamber, issue in a spray from the perforations in the top of the same,and thence pass down through the clothes and through the perforations inthe lateral flanges back into the vertical chamberthe operation beingthus repeated, and all sediment form the clothes collecting in thedepressed bottom of the boiler.

In order to prevent the clothesfrom filling or stopping up theperforations in the lateral flanges d, and prevent them coming incontact with the bottom of the boiler through the perforations in theflanges, which, it has been found, injures and soils the same, due torust or oxidation produced by the lateral flanges and bottom of theboiler coming together, I provide each side of the vertical chamber witha guard or shield, O, which projects from the,

body of the latter, and terminates at such distance from the outer edgesof the lateral flanges as to create a space between the guards and theinner surface of the' walls of the boiler, thereby permitting the freepassage of the water between the same, while the guards hold and supportthe clothes above the perforations in the lateral flanges, therebyaccomplishing the result before mentioned.

The guards are turned down at each end, as at e, and rest upon thelateral flanges, and

are supported intermediate of their length by shoulders f; but it isevident other means of I supporting and retaining the guards willsuggest themselves.

Heretofore wash-boiler attachments or fountains of the class referred tohave been provided with a series of curved strips of metal, one of whichhas been arranged over one row of the perforations in the lateralflanges of the vertical chamber; but in such there is between the stripsof metal intended to support the clothes a series of openings the entirewidth of the attachment, and consequently there is nothing to preventthe clothes passing between the strips, and thereby allowing the clothesto fill 11p the openings and become injured by rust, 850.

In my invention it will be seen that the guards entirely cover thelateral flanges, and effectually prevent any liability of the clothesreaching the perforated lateral flanges.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-- The combination, with an ordinarywashboiler attachment consisting of the vertical chamber perforated atits top, and provided with lateral perforated flanges at its bottom, ofthe guards orshields projecting from the body of the vertical chamber,and entirely covering the lateral perforated flanges, substantially asand for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand.

JOHN RIETH.
